Quantum Threat Looms Over Ethereum and Solana Holders

Quantum computing has the potential to significantly impact various industries, including cryptography and blockchain technology. A recent report from Project Eleven has highlighted the potential threat of quantum attacks on two prominent blockchains: Ethereum and Solana.

The report found that around 65% of Ethereum's users are vulnerable to quantum attacks due to three quantum-vulnerable primitives: ECDSA, BLS signatures, and KZG commitments. These primitives are used for various purposes, including securing user accounts, handling proof-of-stake consensus, and supporting blob data introduced by EIP-4844.

On the other hand, Solana's vulnerability is structural in nature, with its Ed25519 design embedding each wallet's public key directly inside the on-chain address. This makes all Solana users potentially vulnerable to quantum attacks.
